Comparison of the Effect of Warfarin and Direct Oral Anticoagulants on Upper Gastrointestinal System Bleeding

In this study, it was aimed to compare the frequency of new oral anticoagulants and warfarin usage, and to reveal the rates of recurrent upper gastrointestinal bleeding among patients who applied to our hospital with upper gastrointestinal bleeding

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

The data of all patients who applied to Samsun Training and Research Hospital Internal Medicine with a diagnosis of upper gastrointestinal bleeding and hospitalized by Internal Medicine and Gastroenterology clinics or who underwent outpatient endoscopy between 01.01.2021 and 31.12.2021 were included. The patients' data were analyzed from the patient files and hospital automation system retrospectively. Patients who had recurrent upper GI bleeding were detected by controlling them over the hospital software system and by reaching each patient again. The frequency of the new generation oral anticoagulants usage in patients with re-bleeding was determined, and data such as re-bleeding rate, length of hospital stay, need for transfusion, and mortality were analyzed in the groups who did not use this drug and those who used it. The patient demographics were also compared between the groups who were using the new generation oral anticoagulants, acetylsalicylic acid or warfarin.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Patients with recurrent gastrointestinal bleeding
The data of all patients who applied to Samsun Training and Research Hospital for 12 months in 2022 and diagnosis of upper gastrointestinal bleeding and hospitalized by Internal Medicine and Gastroenterology clinics or who underwent outpatient endoscopy were included in the study.Patients who had recurrent upper GI bleeding were detected by controlling them over the hospital software system and by reaching each patient again. The frequency of use of new generation oral anticoagulants in patients with rebleeding was determined, and data such as rebleeding rate, length of hospital stay, need for transfusion, and mortality were analyzed in the groups who did not use this drug and those who used it.
